United StatesPatent 3,185,355 PUP/E FOR LIQUID (IONTAINERS Elmer Lipman, South Lyon,Mich, assignor to Valve Corporation of America, Bridgeport, Conn., 11corporation of Delaware Filed June 4, 1963, Ser. No. 285,418 3 Claims.(Cl. 222341} This invention relates to a pump for liquid containershaving closure and dispenser characteristics. The pump has means forsealing a liquid container for shipping and storage and means foremitting incremental portions of liquid as a dispenser.

Various devices have been developed in the prior art in an attempt toprovide a dispenser-closure pump mountable on a cap which would bothseal the container and dispense the liquid contents of the container.However, these devices were not satisfactory from a commercialstandpoint due to the fact that the liquid contents of the containerleaked out and air leaked into the containers causing evaporation. Inother words, the devices of the prior art did not seal satisfactorilyfor commercial shipping and storage.

With the foregoing in view, the primary object of the invention is toprovide a closure-dispenser pump for a liquid container which is capableof sealing the liquid in the container and sealing air out of thecontainer when not used as a dispenser.

An object of the invention is to provide means for locking thedispensing pump in a sealing position for shipping, storage, and non-useperiods.

An object of the invention is to provide sealing means associated withthe cap and pump structure so that when the pump structure is placed inthe locked position the apertures communicating liquid to use and theorifice communicating atmospheric pressure to the interior of acontainer are sealed off preventing liquid from leaking from thecontainer and preventing air from entering the container.

An object of the invention is to provide means for sealing the pumpchamber between the piston and ball chec valve to isolate the liquid inthe pump chamber relative to both the container and apertures leading toatmoshere. P An object of the invention is to provide a liquid frictionrestriction in the nozzle portion leading from the pump chamber toatmosphere so as to block atmospheric communication to the pump chamberduring the return suction stroke of the piston to fill the pump chamberwith liquid from the container.

These and other objects of the invention will become apparent byreference to the following description of preferred embodiments of theinvention taken in connection with the accompanying drawings in which:

FIG. 1 is a longitudinal cross-sectional view of a pump embodying theinvention shown mounted on the neck of a container with the containerbroken away illustrating the sealed condition.

FIG. 2 is a cross-sectional view of FIG. 1 taken on the line 22 thereof.

FIG. 3 is a view similar to FIG. 1 showing the device in the unsealedand ready to dispense condition; and

FIG. 4 is a longitudinal cross-sectional view of a modified embodimentof the closure-dispenser pump showing the device in the sealedcondition.

Referring now to the drawings where like numerals refer to like andcorresponding parts throughout several views, the sealing-dispensingpumps disclosed therein to illustrate the invention comprise a pumpmounted on a closure cap for liquid containers capable of sealing thecontainer for shipping, storage, and other periods of nonice use, andcapable of dispensing liquid from the container in incremental portionsfor use.

The pump includes a pump chamber communicating with the liquid in thecontainer, a button for operating the pump to draw liquid from thecontainer and to deliver incremental portions of liquid to use. The pumphas means for sealing the liquid dispensing aperture and pump chamber,sealing means for sealing the vacuum break breather orifice leading tothe container, and means for locking the device in a sealed conditionduring idle periods.

More particularly, the cap 10 comprises a central body 11 having aradial flange 12 and annular axial Walls attached to the radial flange12 forming an internal pumping chamber 14.

The annular walls 13 include a hollow stem 15 for attachment to a diptube 16, a ball seat 17 above the stem 15, a spring shelf 18 spacedabove the ball seat 17, and a cylinder 19 rising above the spring shelf18.

Liquid from a container 24} leads through the dip tube 16 past a ball 21on the seat 17 and channels into the cylinder 19. An aperture 22 in theside wall of the cylinder 19 emits liquid from the cylinder to thenozzle 23.

A spring 24 lies in the cylinder 19 and has a lower end resting on thespring shelf 18. A piston 25 lies in the cylinder 19 in contact with theupper end of the spring 24. The spring 24 resiliently urges the piston25 upwardly in the cylinder 19 so as to be manually depressibledownwardly. The boss 26 on the piston 25 lies within the spring 24. Inthe down position of the piston 25, the boss 26 contacts the ball 21 andsealably forces it against the seat 17. This seals the container and thecap at the dip tube connection.

The piston 25 has a head 27 interfitting with a plunger 28 which issurmounted by a button 29 leading to and supporting the annular wall 30.

An outer sleeve 31 surrounds the central body 11 and is connected to thecentral body radial flange 12. The outer sleeve 31 is equipped with abayonet slot 32, a bayonet upper stop 33, and a bayonet lower stop 34.The button wall has a bayonet lug co-acting with the bayonet stops 33and 34 and the bayonet slot 32 of the sleeve 31.

In the position shown in FIG. 3, the bayonet lug contacts the upperbayonet slot 33 and lies in the bayonet slot 32. This is the operativedispenser use position.

In the position shown in FIG. 1, the bayonet lug 35 on the button hasbeen rotated angularly from the position seen in FIG. 3 so as to lieunder the bayonet lower stop 34 on the sleeve 31. This latches thebutton in the sealing position.

Reverse angular movement of the button 29 locates the lug 35 inalignment with the bayonet slot 32 permitting the button to move to theup position shown in FIG. 3. The button moves to the position in FIG. 3after angular movement aligning the lug 35 with the slot 32 by the forceof the spring 24.

The piston 25 has an upper bead 43 sealing against the cylinder 19 inthe upstroke and a lower head 44 sealing against the cylinder in thedownstroke.

In the locked down position of the device the piston 25 lies radially ofthe aperture 22 with the piston beads 43 and 44 sealing off the aperture22.

A vacuum break breather orifice 36 is formed in the central body radialflange 12 and communicates at its lower end with the interior of thecontainer 20 and at its upper end with atmosphere between the buttonwalls 30 and the sleeve 31. The flap seal 32 is disposed over the upperend of the orifice 36 for sealing the orifice in the pump lockedposition.

The button wall 30 presses against the flap seal 32 in the locked downposition forcing the seal 32 against the vacuum break orifice 36 topositively seal off the orifice thereby preventing liquid from thecontainer emitting through the orifice and air from atmosphere fromentering the container.

The nozzle 23 has an outer shell 38 and an inner core 39 in close butspaced relationship thereto. The space 40 between the shell 38 and thecore 39 is in communication with the liquid delivery aperture 22 in thecylinder 19 of the central body 11. The space 46 also communicates withthe nozzle jet 41 which leads directly to atmosphere. The interior ofthe shell 38 and/or the exterior of the core 39 are serrated such aswith helical grooves or flutes so as to force liquid traveling in thespace 40 to travel in a circular path to impart a swirling action to thefluid as it emits from the jet 41.

In the embodiment shown in FIGS. l-3, it will be noted that the outersleeve 31 depends below the central body radial flange 12 and isequipped with threads 45 for coacting with threads 46 on the container20 to attach the cap on the container 24 A sealing washer 47 sealsbetween the radial flange 12 and the top of the con tainer 20. Also inthe embodiments of FIGS. l-3 it is to be noted that the nozzle core 39is formed integral with the central body 11 and that the central body 11has an annular socket formed by the annular axial flanges 48 forreceiving the nozzle shell 38 in concentric spaced relationship to thenozzle core 39.

Referring now to the embodiment seen in FIG. 4, it i will be noted thata central body 60 has an annular flange 61 depending from a radialflange 62. The body annular flange 61 is equipped with threads 63directly connecting the body 60 to a container 64. An outer sleeve 65fits over the central body annular flange 61 and radial flange 62. Theouter sleeve 65 is equipped with the bayonet slots and upper and lowerstops as previously described relative to the outer sleeve 31.

The nozzle 79, FIG. 4, comprises an outer shell 71 and a fluted innercore 72. The central body 60 has an annular socket 73 receiving thenozzle 70 and it is to be noted that the interior of the shell 71 is incommunication with the fluid delivery aperture 76. Fluid received fromthe aperture 76 flows between the shell 71 and the core 72 in the spaceprovided between the flutes of the core 72.

The fluid emits from the nozzle 70 through a jet 74. In

this instance the core 72 is formed separate from the central body 60.The operation of the device shown in FIG. 4 as well as its locked sealedcondition will be understood from the description of the embodimentsshown in FIGS. 1-3.

In assembling the device of the invention, the ball 21, spring 24, andpiston 25v are inserted in the central body 11. The button 29 is thenplaced over the central body 11 with the plunger 28 in contact with thepiston head 27. The flap seal 37 is inserted between the button 29 andthe body radial flange 12. The outer sleeve 31 is then passed overthebutton 29 and pressed into engagement with the body radial flange 12.The dip tube 16 is fixed on the body attaching means 15. The containeris filled with liquid. The sealing washer 47 is inserted within theskirt 49 and the threads 45 are turned on the container threads 46locking the cap 10 on the container 20.

The button 29 is then depressed and turned angularly to locate the lugs35 below the lower stops 34. This moves the button walls 30 in contactwith the flap seal 37 closing ofi the vacuum break breather orifice 36.This also depresses the piston and locates it in a position so that itsboss 26 presses against the ball 21 forcing the ball 21 against the seat17 in a sealed condition. The depressed position of the piston 25 alsolocates the cylinder radially opposite the liquid delivery aperture 22with the piston upper bead 43 and the piston lower bead 44 on eitherside of the aperture 22 isolating it from the chamber 14 closing offcommunication of air and liquid. It closes ofl communication of air tothe cylinder 14 and it closes off communication of liquid from thecylinder 14 to atmosphere through the nozzle 23.

The container with the pump and cap in the down locked position issealed for storage and shipment.

Upon a user obtaining the sealed container, he presses downwardly on thebutton 29 at the same time turning the button 29 angularly so as to movethe lugs 35 from a position lying under the bottom stops 34 to aposition in alignment with the bayonet slots 32. Upon release of thebutton 29, the spring 24 raises the piston 25 and button 29. Upon thepiston 25 and button 29 being raised, the piston boss 26 moves out ofengagement with the ball 21 and the piston 25, moves out of sealingalignment with the outlet aperture 22. The button walls 30 also move offthe flap seal 37 permitting air to pass from the button area thru thevacuum break breather orifice 36 into the container 20.

The user then depresses the button 29 rapidly a few times to activatethe device to fill the chamber 14 with liquid. Upon activation of thedevice, the manual downward movement of the button 29 moves the plunger23 and piston 25 downwardly against the fluid in the chamber 14 whichseats the ball 21 on the seat 17 preventing fluid in the chamber 14 fromemitting back to the container at the ball 21. Upon further downwardmovement of the piston 25 fluid in the chamber 14 moves through theoutlet aperture 22 into the space 40 between the nozzle core 39 and theshell 38 whereupon it is swirled and emitted through the jet 41 in aparticulated spray.

Upon the piston 25 achieving its farthest downward position such as seenin FIG. 1, the user permits the button 29 to rise. Releasing pressure onthe button 29 permits the button 29, plunger 23, piston 25, to moveupwardly in the chamber 14 under power of the spring 24. Thishydraulically pulls the ball 21 upwardly oi? the seat 17 and drawsliquid from the container 20 through the dip tube 16 filling the chamber14. The space 40 between the nozzle core 39 and nozzle shell 38 is soobstructed with fluid and residual liquid in frictional contact with thewalls that any suction at the delivery aperture 22 is resisted by theliquid friction restriction in the nozzle 23. This provides that air isnot drawn into the chamber 14 by the rise of the piston and assures thatliquid is drawn into the chamber 14 by the rise of the piston.

Upon the user emitting the desired quantity of liquid through thenozzle, he depresses the button 29 to the bottom position shown in FIG.1 and turns the button 29 angularly to dispose the button bayonet lugs35 under the lower stops 34 onthe outer shell 31. This locks the button29 and piston 25 in the down position with piston boss 26 pressingagainst the ball 21 forcing it against the seat 17. In this position,the piston upper and lower beads 43 and 44 lie on either side of thedelivery or aperture 22 sealing it off. Also in this downward lockedposition the annular walls 30 on the button 29 are in pressedrelationship with the flap seal 37 urging it into sealing relationshipwith the vacuum break orifice 36 sealing oh the interior of thecontainer in communication therewith.

It is to be understood that the pump devices are shown in enlargedproportion in the figures. The devices are particularly suited forcosmetic, perfume, lighter fluid, oil, and the like in relatively smallsize which can be envisioned when it is to be undenstood that the diptube 16 usually has an internal opening of about %2 of an inch. Theother parts are in the same proportion. While the devices of theinvention are particularly suited for small compact embodiments, it isobvious that larger embodiments can easily be made, such as for thesealing and dispensing of liquid detergents, soaps, etc.

While only two embodiments of the novel pump have been shown anddescribed in detail, it is obvious that many changes may be made in thesize, shape, detail, ar-

rangement of the various elements in the invention within the scope ofthe appended claims.
